To all whom "it may concern:

Beit ,known that I, PHILIP J. MEAI-IL, a citizen of the United States of America, and residel'it' of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Machines for Making Per, forated Music. of which the following is a specification.

My invention relates more particularly to machines which are capable of duplicating or reproducing in a sheet of paper the open- I g ordinarily r In a machine characterized by my invention, the punching devices for making the mary selectors, the said primary selectors consisting, preferably, of pivotedor rockmg fingers adapted to engage the under s de of nection between these primar. selectors and number of intermediate selectors, the primary selectors being actuatedor moved by gravity only, whereby the pattern or mastersheet is not liable to be tornor injured fingers. For this reason, it is possible to employ an ordinary. piece of perforated music as the pattern or master-sheet, it being evident that the provision of primary selectors and intermediate selectors, permits of the use ofla very thin or ordinary sheet of paper-as the pattern or master-sheet, and consequently is of great advantage, as it makesit-unnecessary to employ the usual and specially prepared sheetof thick paper from which to, reproduce or duplicate the perforations. a

Anotherfeature of'my invention consists in an improved construction and arrangement .whereby the, normally inert punches are positively retracted or raised to their normal positions after having been actuated ating thepunches are effectively separated partitions. j r t A further feature of my inventionconsistd an 7 improved feeding 1 arrangementflfor. feeding the paper said arrangement bein other, by means of suitably disposedmet'all'ic and highly efficient manner, and comprising a vibratory feeding clamp adapted to open and close automatically, and arranged to general arrangement involving, -of'course,

suitable means for selectively controlling the punches, whereby efiicient feeding combined with efiicient punchin means in a machine for making perforate music.

The nature tion will, however, hereinafter more fully PP In the accompanying drawings ,-Figure 1 is a side elevation of. machine for perforated. music, of my invention; Fig.2 is a plan of the machine shown in Fig. 1; Fig.3 is a vertical longitudinal section through the machine shown in Fig. 1 5 Fig. 4 is a detail side View on an enlargedscale of a part of the primary selecting mechanism. Fig.5 is a detail making embodying the principles means are and advantages of my invenside View on an enlarged scale of another i portion of the Fig. .6 is also an enlarged detail plan view of a portion of the prima'r selecting mecha-, j

primary selecting mechanism;

tail longitudinal sectional View of the feed- I ingdevice; Fig. 11 is an enlarged detail side, elevation of one of the primary selectors,

showingthe manner in which the same. controlthe intermediate selectors.

As thus illustrated my improved machine for making perforated music comprises a suitable frame or body structure A, adapted to provide suitablebear ngs for the various support the pattern or master-sl1eet, paper,

, etc., n suitably elevated positions.

-" The I machine is driven through "the me- "dium ,of-a belt pulley'B, mounted on an ec-' "centric shaftb, which latter is arranged over,

and transversely of, the frame or body struc 10.5 shafts and-operative parts, and adapted to p titre the direction indicatethby tl1e"'airo\v adjacent thereto,

while the pattern or master sheet and the paper sheet to be punched are drawn or pulled from the front end to the rear end of the machine. Pitmen b are employed as the medium of power transmitting connection between the said eccentric shaft and the constantly vibratingunember 6 This constantly vibrating member b? is pivoted at its rear end 19 so as to swing up and down at its forward end, and constitutes the means for operating the vibrating hammers C. These vibrating hammers are, it will be observed, pivoted at their upper ends to said vibrating member 6 are arranged in a row across the machine, and are thus adapted, in addition to their constant up and down movement, to swing back and forward. The said vibrating hammers are preferably all mounted on a pivot-rod c, which is clamped between a couple of separable blocks a and 0 as shown more clearly 'in Fig. 8, it being observed that the relative formations of the two blocks are such that the rod is held tightly in place. when the two blocks are secured to the bottom of the vibrating member 6 In other words, the blocks have beveled faces which fit together, and the rod is held in a bore formed half in each beveled face. In this way, the vibrating hammers can all be readily removed for repair or substitution, and, if' desired, a separate pin can be provided for each v1- brating hammer.

The punching mechanism (see Fig. 8) mvolves upper and lower dies, D and D, and a number of vertically arranged punches at, corresponding in number to the number of vibratmg hammers. These punches are held in their normally elevated positions by the springs cl, apphed between the top of the upper die D and the cross pins d extendlng through the punches. Each punch is positioned directly below one of the said vibratin hammers, and is thus adapted to be driven through whatever paper or other material may be drawn between the dies. As'

a feature of special improvement, the upper ends of the punches are adapted to work in an upper bar d upon which are mounted the metallic overhangin partitions cl, for separating and controlling the vibrating hammers. In this way, the vibrating hammers are adapted to act smoothly and evenly, and the punches are adapted to be driven through. the paper with force and certainty ofaction. The means for normally maintaining the said vibrating hammers out of position so as not to engage the punches,

consists of a number of longitudinal rods E, connected at their rear ends with the said vibrating hammers, and connected at their forward ends with the vertically disposed and pivoted levers 6. These levers e are I ose aw pivoted at e to the frame or body structure, and are under the constant tension or influence of the springs e'-, which therefore tend constantly to draw the rods E forward in a direction to bring the vibrating hammers into position to act on the upper ends of the punches. The levers e are adapted to act as intermediate-selectors, being provided with horizontal fingers 6 adapted to extend through a perforated plate a and engage the lower ends of the primary selectors F. The lower ends of these primary selectors consist of blocks f provided with notches f, these blocks being adapted to slide up and down in hearings on the plate a". When a notch f is brought into register with the end of a finger 6 it is obvious that the intermediate selector 6, upon which its finger is mounted, will immediately, under the in'luence of one of the springs, draw the corresponding vibrating hammer forward, thereby causing said vibrating hammer, when it descends, to act on the upper end of the corresponding punch. Normally, the blocks J are all up, thereby rendering the interme iate selectors a normally incapable of pulling or drawing the vibrating hammers into 0 erative position. Thus the operation 0 any certain unch 1s dependent upon the downward adustment of the corresponding block f'of the primary selector.

The intermediate-selectors e are detached or disengaged from the notch near the lower ends of the rock-shaft provided with arms 9, connected by sectional rods with a horizontal and forwardl and rearwardly sliding bar This sliding bar, as will be observed, is mounted to extend transversely .of the machine, and directly in front of the vibrating hammers and is moved beneath the overhanging partitions d Therefore each time rimary selectors by means of a the vibrating hammers rise, they are simulshaft G is given the rocking movementnecessary for vibrating the restoring bar 9 that is to say, the bar which eflects theres-. toration of the intermediate-selectors to a position out of engagement with the rimary selectors. The means for control ing the primary selectors F, and thereby selectively controlling the punches through the medium of the intermediate-selectors, comprises a pattern or master-sheet X, of any suitable a or approved character, adapted to travel immediately above the pivotedor rocking fin- ,fingers 7, it being observed at this juncture support of that these fingers are pivotally connected at f with the upper ends f of the rods F which ocks 1. Thus the weight of the blocks f keeps "the pivoted fingers f "foratio'ns in the master-sheet as pressed constantly against the under-side of the pattern or master-sheet. As the mastersheet moves forward, with the paper, the fingers F, b reason of' gravity only, press upon its un er surface and enga ethe per" fi ist as they are brought into register with the ends of the fingers; and assoon as's'ome of the fingers f? engage the perforations in the pattern, or master-sheet, the block f connected with each finger en aging an opening drops down, thereby, as a ready explained, allowing the corresponding fingers e to enter the 'notches f in these blocks, and permitting the. springs e to draw the corresponding vibrating hammers intoposition to engage the corresponding punches.

, The means for restoring the primary selectors to their positions out of engagement with the attern or master-sheet, comprises a vertically reciprocating bar it, adapted to be intermittently raised and lowered by the arms k on the rock-shaft 723. This rockshaft It? is adapted to be rocked or oscillated for the pu1('1pose of lifting the bar vit, the means for so oing consisting preferably f ofa longitudinal rod h? adapted to. engage aspring-lield arm h. on 'said shaft, and provided atitslother end with a roller 'h adapted to engage a cam h on the main shaft 6..

The cam arrangement and connection thus provided effect a raising of the bar it at the proper time, this bar being adapted to engage the joints between thetfingers f and the ro ends f, thereby throwing the .enga ing ends of the fingers 1' down and away rom the pattern or' master-sheet. It will be understood that. the-restoration or disengaging 0f theintermediate selectors E must befirst effected inthe operation of the machine before the bar h is; actuated for the purpose of disengaging; the primary selectors away from the patternfor master-sheet; This is,

of course, accomplished byproperly timing or adjusting the-variouspactuating devices.

The feeding device, which may be employed as the meansforgi'ving the paper-Y toward the rear oft-he machine, and .which an intermittent forward feeding movement mayalso be employed for simultaneously Itherewith drawing thepattern or mastersheet X forward also towardthei rear of the -machine, comprises a. horizontally vibrating,

I and feedin clamp having upper and lower jaws T, connected through the medium of arms 2', z", pivoted togetherat their forward ends. A rock-shaft i is connected through the medium of-crank arms 2' and pitmen a" with the lower arms 2''. of the vibrating feeding clam This clamp is adapted to slide in suit; 1e ways, and its upper jaw is adapted to be drawn-down upon its lower jaw by means of a spring 2' which connects this up er jaw with some suitable portion of the b0 y frame. The rock-shaft i is connected with the main" driving shaft 7) through themedium of a slotted crank-arm a", a rod 2", and a cam i the latter being ada ted to engage a roller 2' on theend of said 'rod". Thus, with this arrangement, the

rotation of the cam i is accompanied at regular intervals by the." oscillation of the shaft 2', resulting in a vibratory movement of thefeeding clamp. The jaws of said feeding clamp are automatically opened and closed at the pro er times, by cams 71 one at each side of t 6 machine, engaging pins or projections on the o posite ends of the jaw I. When the fee ing clamp reaches the limit of this rearward or feeding movement, the said cams operate to open or separate the jaws I and I, and are held open long-enough to permit the feeding clamp to beretracted or drawn back to a position to take a fresh grip on the paper. At the moment the clamp is in position to grip .and-

move the paper forward again, the cams then release thejaw I, allowing the two jaws to come together just as the clamp starts to move in the direction of feed. Thus, in this way, the jaws of the clamp are alternately opened and .closed automatically at the proper times, and, in addition, the clamp is vibrated, so as't'o give the proper or desired intermittentfeeding movement to the paper, it being understood that both the pattern or master-sheet and-the sheets to be punched must remain stationary during the time that the punches are" operated. The feeding clamp grips and feedsthe paper forward as soon as the latter is free from or disengaged by the punches.

.a' matter of further and special improvement, and as a means' for insuring against back movement of the paper during the time that the feeding clamp is being drawn back into position. to take a fresh gripupon the'paper, I provide a gripping or holding clamp, Jcompris'ing the upper and lower 'fjaws J'andJ'. The upper jaw J is mou g'ted on pivoted arms 7', and is adapted to 'ri e'and fall, sons to cooperate with the lowergjaw in" alternately, gripping and releasing the 'pape r. The-jaws J a'nd'J" are opened andfclosed'by the cams j, one ateach side of the machine, adapted to: en-

ga g pins or projections on the opposite ends of the jaw J; As in the case of the feeding *c'lamb, the springs 4' are employed as a [means for pulling the jaw down upon the lower jaw J. A sprocket chain K suitable sprockets mounted, on the main shaft b, and

a shaft it upon" which the said cams 5 andj are mounted, may-be employed as the means for-driving these can1sthat is to say, for

I irotating'itliem in the proper direction to automatically open and close the jaws of the two clamping devices. With this arrangement, the -holding clamp. securely holds the- ;paper against" back .movement, while the feeding clamp is being drawnback to a position totakea fresh grip on the paper, and then-open promptly to releasethe paper as 's'oo'nf'as' the'time arrives for the feeding;

clampto give the 'papenthe desired extent of The extent 0f feed can be varied by adjusting the c'onnectionL along the slot in the arm 2'. The accuracy of the feed can be insured-byadjus'ting the thumb-screw M on .the..-arm :ifl'it being observed that these g'screw's are adapted to vary the distance between .the' axis of the shaft 5 and the point Where the rods i-.conne'ct with't-he arms 2' .The arrangement for accomplishing this ad- 'justmentromprises the said thumb-screw and the adjustable blocks m mounted on the saidarm i and adapted'to be raised and lowered-by. thesaid thumb-screw. Other arrangementsfor, accomplishing the variation of adju s'tlment of the feeding devices, can be,

This I Y'movementiis sufiicient to cause the bar to 'engage the pins d and thereby positively liftthe punches into position to. disengage the paper. The springd may be employed r tracting the punches,

' Ibutjthe provision of the bar N renders the 1 retraction of the punches more certain, it being -understood that it is absolu tialf'tha't the T' hes be prom tly diseny essenperforate music in this manner.

gaged from the paper in order that the latter may have the aforedescribed intermittent feeding mgiement. 1 Witlr .furh ei ..respect t2) the selecting mechanism, the plate H can be yieldingly and adjustably caused to bear upon the upper surface of the .pattern or master-sheet y means of thumb-nuts 0 and springs 0, applied in the manner illustrated. The 1guardo, or rounded supporting piece, can

e employed as a means for preventing the pattern or master-sheet from dragging on the jointed portions of the primary selectors F, or selectors proper. l

It will be seen that the primary selectors are subject to no strain whatever, bein subject only to the force of gravity; an consequently a very thin'sheet of paper may be employed as the pattern or master-sheet it I being. possible,-in fact, to employ for t is purpose a sheet of ordinary perforated music. In otherwords, the fingers or selectors which engage the pattern or master-sheet, are employed for controlling the intermediate selectors, which latter are the ones subject to more or less pressure and strain, and which are connected directly with the ham mers for actuating" the punches". This is of great advantage, inasmuch as it makes it unnecessary to employ a specially constructed pattern or master-sheet, which, as is Well known, usually consists of a com aratively thick sheet of paper provided wit the necessar perforations and. openings, and

' the makm of which is an expensive item in the manu acture of perforated music.. It-

Will be understood, however, that a mastersheet of thick paper can be employed whenever itma be found necessary or desirable to do so. urthermore, it wil beseenthat I provide improved means for actuating the punches, and for retracting the punches, these features being also of advantage, as they render the machine more serviceable and certain in. use.

The"im(proved feeding arrangement, as shown an described, is also an important feature of my invention, as it insures a.

proper and accurate feeding of the paper and master-sheet, a condition which is obviously-ver essential to the manufacture of In operation, it is obvious that the I punches that is to say, those which have been selected for o eration, are 'driven through the paper w ile the selecting and feedingdevices are at rest. As soon as the vibrating hammers which operate the punches start'to rise, the intermediate selectors are restored and disengaged from the primary selectors in the manner described. After this, the primary selectors are then restored and disengaged from the pattern or master-sheet. At this point, everythin being in readiness, the feed'ng clamps fee the;

-pattern or master-sheet and paper forward the desiredor necessary distance, the pri mary selectors that engagetopenings in the master-sheet allowing some of the intermediate selectors to pull some of the vibrating i hammers into osition to engage the correv.are then driven through the "and paper a steady, progressive, movement.

a It will be readily understood that the various cams, cranks, and other power trans nntting LlGVlCQS can be so timed orrelat-lvely adjusted as to cause said ditferentsteps in theoperaticnof the machine to occur at the proper times.

Itwill be seen that the feeding clamp,-composed of the jaWsI and I, is adapted to feed the paper forward, and also the mastersheet, if such is desired; and it is preferable, in any event, that said feeding clamp be adapted and timed to feed the paper while the punches are outof engagement withthe paper; also if the device is used to fit the punching mechanism and controlled by said primary selectors, thesaid punching mechpattern sheet while the primary selectors and also the intermediate selectorsare out of engagement with the masterrsheet. F urthermore,said feeding'clamp'is preferably actuated through the medium of "a pitman hav ing adjustable connection with the slotted arm, these two elements constituting medium of power transmitting connection between i the clamp and the shaft which actuates the hammers for operating the punches. Preferably, as illustrated, both the primary selectors and the intermediate selectors are piv otally'mounted; theprimary selectors being provided with pendent notched blocks which lectors are actuated. And thesepivoted priactas weights to keep the rimary selectors pressed normally against t e under side of the master' sheetyand the, intermediate selectors being subject to spring-tension-tend ring 'to vkeep them pressed against the said blocks or weights by which the prlmary semary selectors and intermediate selectors are, as described and illustrated, preferablyand advantageouslyemployed in combination-with the normally stationary punches. By locating the feeding clamp "between the" punches and the holding'clamp, it is obvious that'the holding clamp will prevent .the feeding clamp from, for any reason what-ever, pulling the paper back in the wrong-direction. In other words, with this relative arrangement of the elements, there is no danger of a reverse motion of the paper, nor of a buckling of the paper during the return stroke of the feeding clamp; and consequently, a very accurate feeding of the paper is insured.

It will be seen that the hammers are pulled into operative ositions by springs throu h the medium 0 horizontally disposed ro s.

machine remain normally at rest during the operation of the machine, and arenot constantly vibrated during the running of the machine, as is the case with certain ma chines prior to my invention. Consequently,

each punch, even while the machine is running, remalns'stationary until actuated by the hammer. Furthermore, the die which cooperates with the punches is always stationary, whetherthe machine is running or not.
